Wiki topic outline

Learning Objective:

• we are learning to estimate and name various angles.

Investing:

• This is useful because it is used in so many aspects of real life.
• A functional (real-life) application is air traffic control, building constructions, data analysis and engingeering
• This skill leads to being able to successfully measure angles (knowing that you are taking the right angle), and use estimates to check that we have a plausible answer.
• This could help you if you want to work in architecture

Preparing:

• Let's be sure you can name the different angles?
• Before you start you need to know that there are 4 main types of angles: acute (less than 90 degrees), obtuse (between 90 and 180 degrees but not equal to either), reflex (between 180 and 360 but not equal to either), straigt line (180 degrees) and angles around a point (360 degrees).

Modeling:

• Here are some examples of angles in real life, can you name them?
• 
• Here are some more examples. Did they get it right or wrong? Explain how you know!

• What do you think common mistakes are?

Discussing:

• How would you explain angles to someone who was new to it?
• Time to test our knowledge, shout your answers and the teacher will shoot the appropriate UFO.

Practising:

• Firstly, we are going to practise estimating bearings.

• Write your answers on your papers, no crossings out will be accepted so think carefully before you write it down.

• In the second column, write the answer when you are shown.

• Finally, find the difference between your estimate and the answer.

• The first second and third smallest differences wll all recieve stickers.

Reflection:

• Reflect in your books how confident you are with estimating angles.

More practise:

• Lets practise categorising angles, on your desks you will find work sheets for you to complete, label the angles and write them in your tables in the correct location.
• 
  

Developing:

• Next we could learn what corresponding, opposite, alternative angles are.
• This leads to solving problems with angles at C grade GCSE.
